they are simple to rebuild bro !...with our help..and you having a service manual ?..chit..it's a walk in the park for you !. you may not even need to tear the motor apart ?..you could have just a bad shifting drum on the left hand side..which is where your foot shifting takes place. it's just in..behind the left hand side cover...all you need to do is get to the shifting shaft part right there ?..and all that has to be done is removing the left hand side cover...drain your oil first though..or..tilt the atv to the right about 45 degree's..so all your oil flows to the right inside the motor..and you won't have a mess when you pull the left hand side cover !.

maybe some ring compressers and ring removal tool too, otherwise you will have a fun time putting the rings on the piston and putting the piston back into the cylinder.

in 15 years, not once have I used a ring compresser to install rings, and get the piston in cylinder, it all can be done with just your fingers, and holding your mouth just right !..lol.

Yeah, same here. I never use them.

If possible, I try to put the cylinder on after the piston is installed on the rod. Makes it a lot easier to get the circlips in.

Two things: After spending a few months on a rebuild for the first time on my 300, all I used were Crafstman sockets with an impact and never had any problems.

And if you can put the bolts back in where they came from or keep them all separated and marked, that will save you a lot of headaches! And take pics before you take everything apart. Fortunately one of my friends has a 300 so I was able to refer to it for putting it back together! Lol I guess that was three things
